HEADLIGHT-DIMMER.

Application led January 30, 1917.

To all u-mm. it may comer/i.'

Be it known that I, Eowaan KILLEBREW, a citizen of the United States. residing' at St. Louis. in the. l*late of Missouri, have invented new and useful Improvements in Headlight-Diinmei-S, of whirh the following is a sperifieation.

This invention relates to headlight dimmers. being especially designed for the headlamps of automaliiles in order to enable drivers to eomply with trailie regulationa in congested distrirts` h v restricting the illumination of the roadway and avoiding the projection of straight ahead or upwardly extend ing rays of light whieh prove dazzling and are therefore dangerous to traffic in general.

One of the chief objects of the present invention is to provide a dimmer which may he easily applied to any headlamp by merely inserting the same in place therein. the dimmer heiner easily removable when the opera.- tor of a machine arrives in the open country Where the tiaflie restrictions do not apply and where he needs the full light from the headlampa.

With the ahove and other objects in view. the invention eonsists in the. novel (',onstrule-1 tion. combination and arrangement of parts. as herein described. illustrated and rlaimed.

Figure 1 is a vertical fore and aft section through n headlamp showing the dimmer of tl'iis invention in its applied relation therein.

Fig. is a rear elevation of the dimmer.

Fig. 3 is a front elevation of the dimmer.

Fig. 4 is a fragmentary #notional view Iahowing one of the retaining devices for the dimmer.

Fig. 5 is a sertional view similar to Fig. l showing the dimmer applied to a headlarrnI of another type.

Fig. G is a rear elevation of the dimmer Shown in Fig. 5.

ll'pferring` to the drawings generally designates a headlamp of any ordinary or preferred ronetrnetion. the same shown as provided with the usual front. glass, len.C or panel l and rontainiu r a Prestodite hurnor 2 or an eleetrie lamp 3 or hoth aS may he preferred.

rlhe dimmi-r vontemplated in thi@ invena disk-Sh ,wd hody i preferably oi' dieet ini-tal. formed with a ventral aperture .'i and :dao provided at one Side of the aperture with a Qorlv'rt tl of tubular formation ha ving a `wt arrow T and a. flange Specification of Letters Patent.

B by which said socket. is secured to the hody 4 hy suitahle fastening means. The hotly 4 of the dimmer is held securely in place hy means4 of a circular series of arcun te springs 9 secured to the marginal portion of the ho'ly l So a to hear against the inner surface of the hody of the lamp A for the purpose ot retaining the body 4 in a Certain li 'ed relation therein and permittingr the dimmer to he removed from the lamp A when not needed. i

Extending through the aperture 5 of the llody l ia a top ray interrepter l() having an attarhin;r flange 11 and a downwardly turned marginal portion or flange 12 the area of whieh is sufficient to obstruct, deflert or interrept the neeesaary number of raya of light. to prevent the blinding of pedestrians or the drivers of other vehicles. iinilar hat smaller hottom ra).7 intereepter lll evtend forwardly from tln` flange l1 t0 prevent the downwardly projerted rays of light from the lamp or burner striking` agaimt the hottom of the reflector and therel v lining projeeted upwardly.

0n its roar sido the hody 4 of the dimmer is provided with a rearwardly projeeting spring elaap lv-l adapted to emhrare the :net vlerm or lreslodite hurner An oleo triflamp enihraeing loop l5 is also arranged in rear of the hody Al of the dimmer and rouneeted thereto h v a Spring ,Shank 16. rl`he spring shank lt ahove referred to is inserted through the Sorket (i and held adjusted h v ilu` arren- 7. The devieea Il and 15 thus provide additional retaining mean;` for the hodlv of the dinnner. l'ly openingr or removin;Ir the front panel l of the lamp the dimmer hrreinahove deserihed may he read ily inserted and removed an found necessary.

llaving thual deaerihed my invention. l claim t-W l. dimmer of the rlasa referred to vom prisinf;v a dialvvshaped hody having a rrntral aperture therein. a top interrepter extendiuf r loro a rdly from Said body at. the upper aide of aid aperture. a bottom intercepter extending! forwardly from lQaid body in line with tlnlower margin otz .will aperture. and resilient meal` (or holding vmid l'iody in po aition in a lamp casan dimmer of the [dans referred to rom` prising a ilialv'-ahap0d hodv havin;r a ventral aperture therein. a top intereeptfr extend ing torwardlv from k aid hody at the upper slide of Said aperture, a liottorn intercepter extending forwardly from said body in lino with thv lower mar in of said aperture, and resilient means [or molding said bod?)y in position in n l-.imp caise said moans em n dymg a cirrnlir Series of sprin Securedto tho marginal portion of the bo( y und adapted to bear zit. their opposite extremities against tlm ina-ide wall of thv. lmnp case.
